BACKGROUND

1. Technical Field

The present invention relates to an optical image lens system. Moreparticularly, the present invention relates to a compact optical imagelens system applicable to electronic products and three-dimensional (3D)image applications thereof.

2. Description of Related Art

In recent years, with the popularity of mobile products with camerafunctionalities, the demand for a miniaturized photographing lensassembly is increasing. The sensor of a conventional photographingcamera is typically a CCD (Charge-Coupled Device) image sensor or a CMOS(Complementary Metal-Oxide Semiconductor) sensor. As the advancedsemiconductor manufacturing technologies have allowed the pixel size ofsensors to be reduced and compact photographing lens assemblies havegradually evolved toward the field of higher megapixels, there is anincreasing demand for photographing lens assemblies featuring betterimage quality.

A conventional compact optical lens system employed in a portableelectronic product, such as the one disclosed in U.S. Pat. No.7,869,142, mainly adopts a four-element lens structure. Due to thepopularity of mobile products with high-end specifications, such assmart phones and PDAs (Personal Digital Assistants), the requirementsfor smaller pixel size and better image quality have been increasing.However, the conventional four-element lens structure cannot satisfythese requirements of the compact optical lens system.

Although other conventional optical lens systems with five-element lensstructure such as the ones disclosed in U.S. Pat. No. 8,000,030 and U.S.Pat. No. 8,000,031 enhance image quality and resolving power, theseoptical designs still reside with unsolved problems. Since there are nothree continuous lens elements closest to the object side with positiverefractive power, it is not favorable for presenting its telephotofunctionality in which the telephoto ratio is thereby limited. Theseoptical designs are also hard to keep the lens system compact whileachieving for the same telephoto ratio. Besides, these optical designsare not favorable for reducing the sensitivity of the lens systembecause its positive refractive power of these optical systems is noteffectively distributed.

DETAILED DESCRIPTION

An optical image lens system includes, in order from an object side toan image side, a first lens element, a second lens element, a third lenselement, a fourth lens element, a fifth lens element, and a sixth lenselement.

Each of the first lens element, the second lens element, the third lenselement, the fourth lens element, the fifth lens element, and the sixthlens element can be a single and non-cemented lens element. That is, anytwo lens elements adjacent to each other (such as the image-side surfaceof the first lens element and an object-side surface of the second lenselement) are not cemented, and there is an air space between the twolens elements. That is, an air distance between two adjacent surfaces ofany two adjacent lens elements. Since the manufacturing process of thecemented lenses is more complex than the non-cemented lenses. Inparticular, a second surface of one lens and a first surface of thefollowing lens need to have accurate curvature to ensure these two lenselements will be highly cemented. However, during the cementing process,those two lens elements might not be highly cemented due to displacementand it is thereby not favorable for the image quality of the opticalimage lens system. Therefore, the optical image lens system of thepresent disclosure can provide six single and non-cemented lens elementsfor improving upon the problem generated by the cemented lens elements.

The first lens element with positive refractive power has a convexobject-side surface, so that the total track length of the optical imagelens system can be reduced by property adjusting the positive refractivepower and the curvature of the object-side surface of the first lenselement.

The second lens element with positive refractive power can enhance thetelephoto functionality of the optical image lens system by combiningwith the positive refractive power of the first lens element, so thatthe total track length thereof can be reduced. The second lens elementhas an image-side surface being concave at a paraxial region and beingconvex at a peripheral region, so the astigmatism and the incident angleof the off-axis field onto an image sensor can be effectively reducedand the aberration can be corrected as well.

The third lens element with positive refractive power can enhance thetelephoto functionality of the optical image lens system by combiningwith the positive refractive power of the second lens element, so thatthe total track length thereof can be reduced. The sensitivity of theoptical image lens system can be reduced by balancing the distributionof the positive refractive power of the first lens element, the secondlens element, and the third lens element.

The fourth lens element with negative refractive power has a concaveobject-side surface and a convex image-side surface. Therefore, theaberration and the astigmatism of the optical image lens system can becorrected.

The fifth lens element with positive refractive power is made ofplastic, and can have a convex object-side surface and a concaveimage-side surface. The object-side surface of the fifth lens elementchanges from convex at a paraxial region to concave at a peripheralregion, and the image-side surface of the fifth lens element changesfrom concave at a paraxial region to convex at a peripheral region.Therefore, it is favorable for correcting astigmatism to obtain goodimage quality by employing the significant curvature variations of theobject-side and image-side surfaces of the fifth lens element.

The sixth lens element with refractive power is made of plastic and hasa concave image-side surface at a paraxial region. The image-sidesurface of the sixth lens element changes from concave at the paraxialregion to convex at a peripheral region. Therefore, a principal point ofthe optical image lens system can be positioned away from the imageplane, and the back focal length of the optical image lens system can bereduced so as to maintain the compact size thereof. Moreover, theincident angle of the off-axis field onto the image sensor can beeffectively reduced and the aberration can be further corrected as wellto increase the receiving efficiency of the image sensor.

When a curvature radius of the object-side surface of the third lenselement is R5, and a curvature radius of the image-side surface of thethird lens element is R6, the following relationship is satisfied:0<(R5+R6)(R5−R6)<3.2. Therefore, it is favorable for correcting thespherical aberration and astigmatism of the optical image lens system byproperly adjusting the curvature radius of the third lens element.

When a focal length of the optical image lens system is f, and a focallength of the second lens element is f2, the following relationship issatisfied: 0<f/f2<1.0. Therefore, the positive refractive power of thesecond lens element can be property adjusted for enhancing the telephotofunctionality of the optical image lens system so as to reduce the totaltrack length thereof.

When the focal length of the second lens element is f2, and a focallength of the third lens element is f3, the following relationship issatisfied: 0<f3/f2<1.6. Therefore, the positive refractive power of thesecond and the third lens elements can be properly adjusted forenhancing the telephoto functionality of the optical image lens systemso as to reduce the total track length thereof. Furthermore, thesensitivity of the optical image lens system can be reduced by balancingthe distribution of the refractive power thereof.

When the focal length of the optical image lens system is f, and a focallength of the fourth lens element is f4, the following relationship issatisfied: −1.90<f/f4<−0.55. Therefore, the aberration of the opticalimage lens system can be corrected by properly adjusting the negativerefractive power of the fourth lens element.

When an Abbe number of the fourth lens element is V4, and an Abbe numberof the fifth lens element is V5, the following relationship issatisfied: 0.20<V4/V5<0.60. Therefore, the chromatic aberration of theoptical image lens system can be corrected.

When the focal length of the optical image lens system is f, and acurvature radius of the object-side surface of the fifth lens element isR9, the following relationship is satisfied: 0<R9/f<0.8. Therefore, theastigmatism of the optical image lens system can be corrected.

When the focal length of the optical image lens system is f, a focallength of the first lens element is f1, and the focal length of thesecond lens element is f2, the following relationships are satisfied:0<|(f/f1|+f/f2|<1.3. Therefore, the refractive power of the first lenselement and the second lens element are proper, so that the telephotofunctionality of the optical image lens system can be enhanced forreducing the total track length thereof.

When a maximal field of view of the optical image lens system is FOV,the following relationship is satisfied: 70 degrees<FOV<100 degrees.Therefore, the proper field of view of the optical image lens system canreduce image distortion so as to improve image quality.

The surfaces of the first lens element through the sixth lens elementcan be meniscus at a paraxial region thereof. A meniscus lens elementindicates that one surface of the lens element is concave at a paraxialregion and the other surface of the lens element is convex at a paraxialregion. Therefore, the astigmatism of the optical image lens system canbe corrected.

When an axial distance between the first lens element and the secondlens element is T12, an axial distance between the second lens elementand the third lens element is T23, an axial distance between the thirdlens element and the fourth lens element is T34, an axial distancebetween the fourth lens element and the fifth lens element is T45, andan axial distance between the fifth lens element and the sixth lenselement is T56, and T56 is the largest axial distance among T12, T23,T34, T45, and T56. Therefore, it is favorable for assembling the lenselements to enhance the manufacturing yield rate by properly adjustingthe distance between each lens element.

The refractive power of the sixth lens element can be stronger than therefractive power of the first lens element. That is, the absolute valueof the refractive power of the sixth lens element can be greater thanthe absolute value of the refractive power of the first lens element.The refractive power of a lens element can be calculated by thereciprocal of its focal length value.

According to the optical image lens system of the present disclosure,the lens elements thereof can be made of plastic or glass. When the lenselements are made of glass, the allocation of the refractive power ofthe optical image lens system may be more flexible and easier to design.When the lens elements are made of plastic, the manufacturing cost canbe effectively reduced. Furthermore, the surface of each lens elementcan be aspheric, so that it is easier to make the surface intonon-spherical shapes. As a result, more controllable variables areobtained for reducing the aberration, and the number of required lenselements for constructing an optical image lens system can be reduced.Therefore, the total track length of the optical image lens system canalso be reduced.

According to the optical image lens system of the present disclosure,each of an object-side surface and an image-side surface of every lenselement has a paraxial region and a peripheral region. The paraxialregion refers to the region of the surface where light rays travel closeto an optical axis and the peripheral region refers to the region of thesurface where light rays travel away from the optical axis.Particularly, when a lens element has a convex surface, it indicatesthat the surface is convex at a paraxial region; and when a lens elementhas a concave surface, it indicates that the surface is concave at aparaxial region.

According to the optical image lens system of the present disclosure,the optical image lens system can include at least one stop, such as anaperture stop, a glare stop or a field stop. Said glare stop or saidfield stop is for eliminating the stray light and thereby improving theimage resolution thereof.

In the present optical image lens system, an aperture stop can beconfigured as a front stop or a middle stop. A front stop disposedbetween an object and the first lens element can provide a longerdistance between an exit pupil of the system and an image plane andwhich improves the image-sensing efficiency of an image sensor. A middlestop disposed between the first lens element and an image plane isfavorable for enlarging the field of view of the system and therebyprovides a wider field of view for the same.
